These are specialized terms used in the analysis of the composition of petroleum products; they represent abbreviations for n-paraffins, isoparaffins, olefins, naphthenes, and aromatics in petroleum mixtures: P – Paraffins, n-paraffins; I – Isoparaffins, isoparaffins; O – Olefins, olefins; N – Naphthenens, naphthenes; A – Aromatics, aromatics. These terms can be easily found in academic sources. Previous posts must have relevant content. In laboratory chromatographic analysis, a full analysis of all components is typically carried out first to identify them qualitatively, after which they are classified and their amounts are added together. During online chromatographic analysis, group analysis can also be employed; the retention differences of different categories on the chromatography column can be utilized for such grouping. Whether it is laboratory chromatographic analysis or online chromatographic analysis, capillary chromatography columns are often used for the analysis. This analysis is commonly used in the analysis of olefin cracking, reforming feedstocks and products, and gasoline composition.
